Which of the following had the smallest brain capacity?
1. Homo erectus
2. Homo sapiens
3. Homo neanderthalensis
4. Homo habilis
2. there are no mutations
3. there is no migration
4. the population is large
In a population of 1000 individuals, 360 belong to genotype AA, 480 to Aa and the remaining 160 to aa. Based on this data, the frequency of allele A in the population is:

| 2. | Analogous organs that have evolved due to convergent evolution. |
| 3. | Analogous organs that have evolved due to divergent evolution. |
| 4. | Homologous organs that have evolved due to convergent evolution. |
